The dos and don'ts of cloning new bitches, about ten? (9)
I believe the answer is:
bioethics
'the dos and don'ts of cloning' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'new bitches about ten?' is the wordplay.
'new' is an anagram indicator.
'about' is an insertion indicator.
'ten?' becomes 'io' (IO resembles 10).
'bitches' with letters rearranged gives 'bethics'.
'bethics' going around 'io' is 'BIOETHICS'.
Can you help me to learn more?
(Another definition for bioethics that I've seen is " Moral aspect of medical research".)
